Operation Overview
- After being powered up, the 7-seg display will show the input voltage value
- Red Relay State Indication LED: ON indicates relay coil is energized and voltage is present at output terminals / OFF indicates relay coil is deenergized and no voltage is present at output terminals
- “+” Button Short Press: Display the undervoltage cutoff value. Relay will turn OFF (open normally open contacts) when input voltage falls below this value
- “+” Long Press: Set the undervoltage cutoff value. Hold button press until value starts flashing, then use “+” and “-” buttons to adjust value
- “-” Button Short Press: Display the hysteresis value. Undervoltage cutoff value + Hysteresis value = Voltage at which input voltage needs to rise above before relay will turn ON (close normally open contacts)
- “-” Long Press: Set the hysteresis value. Hold button press until value starts flashing, then use “+” and “-” buttons to adjust value.
